摘要
根据织金洞的区域地质(即地层、构造、地貌等)条件以及水文地质特点,笔者等在该洞采起了八个地质样品。进行铀系年龄测定.文章着重介绍了该洞八个样品铀系测定的方法、原理、测试技术、测试结果,并通过结果分析,对织金洞以及洞中某些重要洞石的形成原因、机理、模式作了初步探讨.
The authors of this article have been to Zhijin Cavern for several times to make investigatons and have collected eight geological samples. The U isotopic geological age measurement of the samples were separately made. Based on the measurement results and according to the geological and hydrogeological conditions in that region, the authors deal with the origin mechanism and models of some important rocks of Zhijin Cavern in this article.
The development of the form of Zhjjin Cavern can be divided into two main stages: the early stage of the horizontal cavern development and the late stage of the funnel-like cavern development. The appearance of the latter karst development stage is in relation to the structural formation of carbonate rock strata and the new structural movement of the intervallic rise of Yunnan-Guizhou Plateau, showing continuing development characters of palaeokarst water nets. But the formation of those special stones of the cavern are in relation to the development of the special funnel-like cavern.
